Ruth 3:7 And when Boaz had eaten and drunk, and his heart was merry, he went to lie down at the end of the heap of grain. Then she came softly, and uncovered his feet, and lay down.
8 At midnight the man was startled, and turned over, and behold, a woman lay at his feet! 9 He said, "Who are you?" And she answered, "I am Ruth, your maidservant; spread your skirt over your maidservant, for you are next of kin."
10 And he said, "May you be blessed by the LORD, my daughter; you have made this last kindness greater than the first, in that you have not gone after young men, whether poor or rich.
11 And now, my daughter, do not fear, I will do for you all that you ask, for all my fellow townsmen know that you are a woman of worth.
12 And now it is true that I am a near kinsman, yet there is a kinsman nearer than I.
13 Remain this night, and in the morning, if he will do the part of the next of kin for you, well; let him do it; but if he is not willing to do the part of the next of kin for you, then, as the LORD lives, I will do the part of the next of kin for you. Lie down until the morning."
14 So she lay at his feet until the morning, but arose before one could recognize another; and he said, "Let it not be known that the woman came to the threshing floor."
Ruth 4:1 And Boaz went up to the gate and sat down there; and behold, the next of kin, of whom Boaz had spoken, came by. So Boaz said, "Turn aside, friend; sit down here"; and he turned aside and sat down.
2 And he took ten men of the elders of the city, and said, "Sit down here"; so they sat down.
3 Then he said to the next of kin, "Naomi, who has come back from the country of Moab, is selling the parcel of land which belonged to our kinsman Elimelech.
4 So I thought I would tell you of it, and say, Buy it in the presence of those sitting here, and in the presence of the elders of my people. If you will redeem it, redeem it; but if you will not, tell me, that I may know, for there is no one besides you to redeem it, and I come after you." And he said, "I will redeem it."
5 Then Boaz said, "The day you buy the field from the hand of Naomi, you are also buying Ruth the Moabitess, the widow of the dead, in order to restore the name of the dead to his inheritance."
6 Then the next of kin said, "I cannot redeem it for myself, lest I impair my own inheritance. Take my right of redemption yourself, for I cannot redeem it."
7 Now this was the custom in former times in Israel concerning redeeming and exchanging: to confirm a transaction, the one drew off his sandal and gave it to the other, and this was the manner of attesting in Israel.
8 So when the next of kin said to Boaz, "Buy it for yourself," he drew off his sandal. 9 Then Boaz said to the elders and all the people, "You are witnesses this day that I have bought from the hand of Naomi all that belonged to Elimelech and all that belonged to Chilion and to Mahlon.
10 Also Ruth the Moabitess, the widow of Mahlon, I have bought to be my wife, to perpetuate the name of the dead in his inheritance, that the name of the dead may not be cut off from among his brethren and from the gate of his native place; you are witnesses this day."
11 Then all the people who were at the gate, and the elders, said, "We are witnesses. May the LORD make the woman, who is coming into your house, like Rachel and Leah, who together built up the house of Israel. May you prosper in Ephrathah and be renowned in Bethlehem;
12 and may your house be like the house of Perez, whom Tamar bore to Judah, because of the children that the LORD will give you by this young woman."
13 So Boaz took Ruth and she became his wife; and he went in to her, and the LORD gave her conception, and she bore a son.
14 Then the women said to Naomi, "Blessed be the LORD, who has not left you this day without next of kin; and may his name be renowned in Israel!
15 He shall be to you a restorer of life and a nourisher of your old age; for your daughter-in-law who loves you, who is more to you than seven sons, has borne him."
16 Then Naomi took the child and laid him in her bosom, and became his nurse.
17 And the women of the neighborhood gave him a name, saying, "A son has been born to Naomi." They named him Obed; he was the father of Jesse, the father of David.

1Ti 5:11 But refuse to enrol younger-women [Gr. ne(o)teras] widows [Gr. ch(e)ras]; for when they grow wanton against Christ they desire to marry,
1Ti 5:12 and so they incur condemnation for having violated their first pledge.
1Ti 5:14 So I would have younger women [Gr. ne(o)teras] marry, bear children, manage their households, and give the enemy no cause to revile us.
